It is always failing and crashing ...

[13:18:48]: Unable to find any .xccoverage file.
[13:18:48]: Make sure you have enabled 'Gather code coverage' setting on your scheme settings.
[13:18:48]: Alternatively you can provide the full path to your .xccoverage file.

...

/Users/user/.rvm/gems/ruby-2.4.1/gems/xcov-1.4.0/lib/xcov/error_handler.rb:20:in `handle_error': [!] Error creating your coverage report - see the log above (RuntimeError)

... which does not make sense since I am using Xcode 9.3 (which is using .xccovreport format).

Gather code coverage option is enabled/checked.

Is there another way to configure the xcov lane in order to make it work properly?

Try manually passing in the derived data folder. For example:

BUILD_PATH="./build"
DERIVED_DATA_PATH = "#{BUILD_PATH}/derived_data"
PROJECT_NAME='BonMot.xcodeproj'

...

  begin
    scan(
      output_types: 'junit,html',
      devices: devices,
      destination: destination,
      scheme: scheme,
      output_directory: scan_output_path,
      code_coverage: true,
      derived_data_path: DERIVED_DATA_PATH,
      result_bundle: true,
      disable_concurrent_testing: disable_concurrent_testing
    )
  rescue => ex
    # Don't fail the entire lane when running tests, but print failure to STDERR
    STDERR.puts ex
  end

  xcov(
    project: PROJECT_NAME,
    scheme: scheme,
    output_directory: "#{BUILD_PATH}/#{scheme}/xcov",
    derived_data_path: DERIVED_DATA_PATH
  )

Xcode 9 has changed the way it stores coverage reports Xcode 9.3 also includes a new command line tool to represent coverage data in both human-readable and machine-parseable format: xccov (see man xccov)

In general there are now two files instead of one: .xccovreport and .xccovarchive. The coverage report contains line coverage percentages for each target, source file, and function/method that has coverage information. The coverage archive contains the raw execution counts for each file in the report

Same issue.

Hi @eMdOS @markobyte 👋

Can I see the arguments you're passing to xcov? Thanks :)

[hungrxyz]

I'm trying to use it with BuddyBuild following this tutorial: https://www.buddybuild.com/blog/using-danger-ci-with-buddybuild

xcov.report(  
   scheme: ENV['BUDDYBUILD_SCHEME'],
   workspace: "#{ENV['BUDDYBUILD_WORKSPACE']}/xx.workspace",
   minimum_coverage_percentage: XX,
   derived_data_path: ENV['BUDDYBUILD_TEST_DIR'],
)

[nakiostudio]

@markobyte is BuddyBuild running Xcode 9.3? and the latest version of xcov?

Also, could you try with derived_data_path: "/tmp/sandbox/#{ENV['BUDDYBUILD_APP_ID']}/bbtest" instead of derived_data_path: ENV['BUDDYBUILD_TEST_DIR']?

[hungrxyz]

Stupid mistake on my side. For some reason I though BuddyBuild is doing bundle update. Works after updating the bundle locally.

[nakiostudio]

Thanks for the update @markobyte 👍. It's always tricky to draw line between the things BB does automatically and the things you need to do by yourself.

Closing for lack of activity.
